ses code disappeared after wire mod
ses code disappeared after wire mod so weird thing happened today. i did the wire mod by de-pinning the connectors, labeling them, rerouting and reinstalling. i had previously done !egr and !air so i have been throwing the two codes. after all is said and done i turn on my car to make sure everything is a ok and go to check my codes and now i only have p0405. so somehow the air system code (cant remember the code) has deleted itself from my system? i took it for a quick spin around the block checking the codes as i drive (gotta love using torque on my phone) and it never popped back up. is this something i should be worried about?
No. I recall that the PCM will remove very old codes that haven't been triggered in X number of cycles. If you look up the specific code, you should be able to confirm the conditions that its set and removed.
